If set up, this hub will be used to subscribe to feeds that don't specify a hub of their own.
Assumes that the fallback hub will, in fact, handle polling and updates for any feed we throw at it!
Authentication may be specified for the fallback hub.
Example:
$config['feedsub']['fallback_hub'] = 'https://superfeedr.com/hubbub';
$config['feedsub']['hub_user'] = 'abcd';
$config['feedsub']['hub_pass'] = 'ckcmdkmckdmkcdk';
Also:
* Fix for WordPress-RSS-via-Superfeedr-Atom; if we have <author> info but no ID from a native ActivityStreams actor, don't freak out in the low-level processing code that checks for identity matches.
* enhanced messages for low-level FeedSub exceptions if they make it to outside display
SubMirror: redid add-mirror frontend to accept a feed URL, then pass that on to OStatus, instead of pulling from your subscriptions.
Profile: tweaked subscriberCount() so it doesn't subtract 1 for foreign profiles who aren't subscribed to themselves; instead excludes the self-subscription in the count query.
Memcached_DataObject: tweak to avoid extra error spew in the DB error raising
Work in progress: tweaking feedsub garbage collection so we can count other uses
The ensure* family of functions will now return an OStatusShadowException in this case, which gives us a pleasant error message instead of a giant exception backtrace when you do 'sub somebody@this.local.server'.
Can be extended later to allow actually using the local profile, since we could figure it out.
Conflicts:
lib/attachmentlist.php
plugins/OStatus/classes/Ostatus_profile.php
Merge tried to delete things that it seems it shouldn't, very confusing order. Hope rest of the cherry-picking isn't a problem.
* drop OStatusPlugin::localProfileFromUrl(), we can just look up on user.uri
* clean up a few edge cases that returned null through Ostatus_profile::ensure* code paths, now throws clear exception when we can't find a feed from the given profile url
* add some doc comments on the ensure* methods
Superfeedr (sp.?) posts entries without author information. We can
assume that this is intended to be by the original author.
Re-structured the checks for entries that come in by PuSH so they can
either have no author or an empty author, but not a different author.
Base problem is that our caching-on-insert interferes with relying on column default values; the cached object is missing those fields, so they appear to be empty (null) when the object is retrieved from cache.
Now explicitly setting them when inserting subscriptions, and cleaned up some code that had alternate code paths.
May also have made auto-subscription work for remote OStatus subscribers, but can't test until magic sigs are working again.
Some stray shadow entries were ending up getting created, which would steal group posts from remote users.
Run plugins/OStatus/scripts/fixup-shadow.php for each site to remove any existing ones.
Also stripping id from foreign HTML messages (could interfere with UI) and disabled failing attachment popup for a.attachment links that don't have a proper id, so you can click through instead of getting an error.
Issues:
* any other links aren't marked and saved
* inconsistent behavior between local and remote attachments (local displays in lightbox, remote doesn't)
* if the enclosure'd object isn't referenced in the content, you won't be offered a link to it in our UI
